This chapter describes the development, operation, and experimental results of the Third Generation JPL Electronic Nose (ENose), which operated on board the International Space Station (ISS) as a technology demonstration for seven months from 2008-2009. The JPL ENose is an array of chemiresistive sensors designed to monitor the environment for the sudden release of targeted chemical species, such as leaks or spills. The Third Generation JPL ENose was designed to detect, identify, and quantify eleven chemical species, three inorganic, ammonia, mercury, and sulfur dioxide, and eight organic compounds, which represent common classes of organic compounds such as alcohols, aromatics, and halocarbons. Chemical species were quantified at or below their 24 hour Spacecraft Maximum Allowable Concentrations (SMAC), generally in the parts-per-million range; some targeted species were detected in the parts-per-billion range. Analysis of third generation JPL ENose monitoring data on ISS show the short term presence of low concentrations of alcohols, octafluoropropane, and formaldehyde as well as frequent short term unknown events. Repeated unknown events were identified post-flight as sulfur hexafluoride.

INTRODUCTION: The effects of long-duration (213.0 ± 30.5 d) stays aboard the orbital station Mir and short-term (∼10 d) spaceflights aboard the International Space Station (ISS) on the joint torques of various muscles and work capacity of knee extensors were studied in male cosmonauts.METHODS: Joint torque and muscle endurance testing was performed 30 d before and 3–5 d after a spaceflight, using a LIDO® Multi-Joint Isokinetic Rehabilitation System (USA).RESULTS: Greater postflight changes in maximal joint torque were observed for back, knee, and ankle extensors compared with flexors, and the difference was especially clearly seen after long-term spaceflights. The decrease in maximal joint torque of hip extensors substantially varied, being the greatest in voluntary concentric movements in a low-velocity high-force mode at angular velocities of 30 and 60° · s−1 (by 16 and 13%, respectively) and the lowest in high-velocity modes at velocities of 120 and 180° · s−1 (by 9 and 11%, respectively). Muscle work capacity was inferred from the gradient of declining muscle force produced in a series of rhythmic voluntary concentric movements and was found to decrease after both short- and long-term spaceflights. The area under the muscle contraction curve decreased to a greater extent and in all regions of the curve after long-term spaceflights. The fatigue index averaged 0.90 ± 0.03 at baseline and remained much the same, 0.90 ± 0.04, after a short-term spaceflight. However, after a long-duration spaceflight, the fatigue index increased 14.1%.DISCUSSION: The finding that the contractile functions and work capacity of muscles decrease more after long-term than after short-term spaceflights in spite of the physical training program of a certain type gave grounds to assume that physical training employed in long-term spaceflights were insufficient to simulate the daily mechanical load that the cosmonauts had before a spaceflight.Koryak YA.
